What is the meaning of Virtual?

In effect or essence, rather than in fact or reality; also, imitated, simulated.

For practical purposes, though not technically; almost complete, very near.

1. Operating using a computer and/or online rather than physically present.

   Operating using a computer and/or online rather than physically present.

   Simulated in a computer and/or online.

   Of a class member: capable of being overridden with a different implementation in a subclass.

   Pertaining to a theoretical infinitesimal velocity in a mechanical system that does not violate the system's constraints; also, of other physical quantities: resulting from such a velocity.

   1. Pertaining to a theoretical quality of something which would produce an observable effect if counteracting factors such as friction are disregarded; specifically, of a head of water: producing a certain pressure if friction, etc., is disregarded.
   2. Chiefly in virtual focus: of a focus or point: from which light or other radiation apparently emanates; also, of an image: produced by light that appears to diverge from a point beyond the reflecting or refracting surface.

      1. Having efficacy or power due to some natural qualities.
         1. Of a plant or other thing: having strong healing powers; virtuous.
      2. Having the power of acting without the agency of some material or measurable thing; possessing invisible efficacy.
      3. Producing, or able to produce, some result; effective, efficacious.
      4. Synonym of virtuous (“full of virtue; having excellent moral character”)
